Data Merge
Merge data from CSV or Excel into PDF templates. Generate personalized documents.
Need certificates, tickets or letters with different names from a spreadsheet? With PDF.dk you merge Excel or CSV data into a PDF template for free — place the fields visually and generate one document per row. The servers are located in the Nordics, and files are removed automatically after processing.
Frequently Asked Questions
- What data formats are supported?
- We support CSV and Excel (.xlsx) files with your data rows.
- How do I define fields?
- Use {{fieldname}} syntax in your PDF template. Field names match column headers.
- How do I make certificates with names from Excel?
- Upload your certificate as the PDF template and your Excel sheet with the names. Place the name field on the template, choose font and size, and generate — you get one certificate per row in the sheet.
- Is this a free mail merge for PDF?
- Yes, it works like mail merge but with PDF output: one PDF template plus your rows of data produces many personalised PDF documents, free and without watermark.
- Can I get all documents in one file or as separate files?
- Both. Choose between one combined PDF containing every document or a ZIP with a separate PDF per row — for sending them out individually, for example.
- Can I use my own font?
- Yes, besides standard fonts and Google Fonts you can upload your own font (TTF/OTF) so merged fields match your design. CMYK colours are supported for print too.
- Is it safe to upload my PDF?
- Yes. Your document is processed in the Nordics over an encrypted connection and deleted automatically soon after. We never keep or share your files.
